PI Xls design for SC1225K innoswitch design

Hello John,

Thank you very much for considering using Power Integration Products.

Before we go to the next step, i have a few questions about this board.

Where did you get this Demo Board, from any of our FAE or get it online somewhere?

What's the application for this design, charger or anything else?

Best Regards

Hi PI-YY,

we got this board from PI ShenZhen China. Our company is in France, but we have an employee in China.

This design is for a USB Charger. I need to adapt this design to our manufactoring process, that is why i need information about design calculation.

Thanks

Hello John,

Hi PI-YY,

I didn't receive any information from my FAE.

So, i decided to enter the design in PIXls designer.

I have supposed that SC1225K is INN2024K, I have also adjusted VOR and VB, to get NP and NB values. But Lp=512 µH instead of 640 µH !

Could you please help me.

Thanks

Hello john-lewis66,

Can you also give me the schematic and the transformer information you use. I will try to duplication the PIxls design.

Best Regards

Hi PI-YY,

You can find all data in the attached file.

Can you confirm SC1125K is identical to INN2024K ?

Thanks for your help.
